This application is the U.S. National Phase Application of PCT/EP2013/063662, filed Jun. 28, 2013, which claims priority to German Patent Application No. 10 2012 013 210.7, filed Jul. 4, 2012 and German Patent Application No. 10 2012 224 173.6, filed Dec. 21, 2012, the contents of such applications being incorporated by reference herein.
FIELD OF THE INVENTIONThe invention relates to a fastening device for fixing a cable.
BACKGROUND OF THE INVENTIONThe technical problem on which the invention is based When laying cables or flexible supply lines in a route-bound manner in space, said cables or flexible supply lines have to be fastened at fixing points. This is done either by fixing means (so-called brackets) on the main structure, said fixing means receiving a cable or flexible supply line, or fixing means which are fitted to the cable or flexible supply line and are connected to the main structure by means of a joining method. Rigid fixing means are usually fitted to cables or flexible supply lines. Said rigid fixing means are fixedly connected in a preliminary assembly process, so that the fixing means are axially rotated during the laying process on account of the route guidance. A separate fixing means is used for each type and situation of joining connection. The fixing means generally have several parts. During laying, the cable or the flexible supply lines have to be rotated into the appropriate joining position by applying force. The stresses introduced in this way continue from joining position to joining position, and adversely affect the laying rate and the accuracy of the route.
1. Prior Art
An attempt is made to follow the route as accurately as possible by axially orienting the fixing means during assembly. This involves a high level of expenditure on assembly and testing and therefore expense. Bearing points are fitted in a separate manufacturing process (injection-molding, shrink-fitting). Furthermore, annular fixing means which can be closed on one side and can freely rotate in the axial direction are mounted. This involves an additional manufacturing step and therefore expense. Changes in the position on the cable or the flexible supply line are associated with a high level of expenditure.
SUMMARY OF THE INVENTIONAn aspect of the invention proposes a fastening device for fixing at least one cable, which fastening device is relatively inexpensive and/or reliable and/or allows improved or simple mounting of at least one cable and/or improves the fixing of the cable with respect to the flexible and, in this case, in particular defined orientation of the cable.
The fastening device according to an aspect of the invention for fixing at least one cable comprises, preferably, a clip for receiving and/or fixing a cable, wherein the clip is designed such that it can or does at least partially engage around the cable and can or does clamp said cable in a force-fitting and/or interlocking manner, and wherein the fastening device has a fixing element which comprises a guide element and a retaining element, wherein the guide element is mechanically connected to the clip, and the retaining element is designed such that it allows the fastening device to be mounted in a fixed position.
It is preferred for the guide element to be mounted in the clip in a mount which at least partially surrounds the clip with respect to its casing surface. This is to be understood to mean, in particular, that the guide element is mounted in the at least partially surrounding mount, of the clip itself.
It is expedient for the at least partially surrounding mount of the clip to have two grooves for mounting the guide element, said grooves being designed such that they each receive an edge or side of the guide element, and in particular wherein the grooves are each designed substantially along the curvature of the casing surface.
The guide element preferably has a panel which, or the base surface of which, is substantially in the form of a casing surface segment of a cylinder and/or in particular is designed to correspond to the curvature profile of the casing surface of the clip or is designed depending on said curvature profile.
It is preferred for the clip to be designed such that it can engage around a cable at least partially in a force-fitting manner and fix said cable, so that the cable is secured against rotation and displacement in the clip by the clip having retaining means, in particular retaining ribs, which can clamp the cable on its outer circumference.
The retaining means of the clip are expediently in the form of retaining ribs and/or retaining protrusions and/or retaining fins.
The retaining ribs of the clip are particularly preferably hollow and/or not solid and also elastic. The retaining ribs very particularly preferably have a wall thickness which is lower than one third or, in particular, one fifth of the average width of the retaining ribs or of the height of the retaining ribs.
It is expedient for the retaining ribs to be substantially trapezoidal with respect to their cross-sectional area and/or their profile, in particular the inwardly facing side surface of the retaining ribs, which is designed to mount the cable, is rounded, wherein the rounded portion is in the form of a recess in the top surface of the retaining ribs.
It is preferred for the clip to be of integral design, wherein it has two segments which are connected to one another on one side, in particular by means of a film hinge and/or by means of an elastic web, and wherein the other side can be folded open and folded closed and has an interlocking closure means.
The mount, comprising the two grooves, and also the guide element which is mounted in this mount are expediently designed such that relative movements along the curvature or the circumferential line of the casing surface of the clip between the clip itself and the fixing element are possible.
The inside diameter of the space spanned by the retaining ribs of the clip is preferably somewhat smaller than the outside diameter of the cable or flexible supply line which is to be received and clamped. Owing to the mechanical stress or force-fitting clamping generated as a result, a clamping action or an interlocking connection between the cable and retaining ribs is generated in particular, wherein the cable and retaining ribs are each slightly deformed. This prevents an axial relative movement or displacement between the cable and the clip.
Grooves which receive the semicircular mating segment of the variable fixing means by means of an undercut are expediently fitted on the first and second segments of the clip, in particular centrally or symmetrically with respect to the central cross-sectional area through the clip. Before the cable or the flexible supply line is deposited and the clip is folded closed, the guide element of the fixing element is placed or inserted into the mount which is formed by the grooves.
It is expedient for the at least one retaining element of the fixing element to be in the form of a tap or arrowhead or “Christmas tree”. In this case, the retaining element is designed, in particular, such that it can be inserted into a recess or bore, particularly preferably in a vehicle body, and can be fastened and can be fixed therein.
The invention also relates to the use of the fastening device for fixing at least one cable in motor vehicles, in this case in particular for fixing the cable of a wheel rotation speed sensor to the vehicle body and/or to attached parts of the vehicle or the vehicle body.
Further preferred embodiments can be found in the dependent claims and the following description of an exemplary embodiment, with reference to figures.
The mount 11, comprising the two grooves 12, and also the guide element which is mounted in this mount, see
The clip 1 also comprises a closure means 18 which connects or can connect the two segments 15, 16 in an interlocking manner and closes or can close the clip, wherein the closure means is designed such that this closing operation takes the form of a linking operation and/or latching operation.
In
In
In this case, the retaining ribs 13 are elastically and/or plastically deformable according to the example, as a result of which the transmission of force to the cable or an adhesion fit of the cable on the retaining ribs 13 of the clip 1 is ensured or possible or implemented.
The fastening device is shown in a side view with an inserted or clamped cable 3 with reference to
